It’s time people start asking why is a shot free but not the preventative medicine nor the treatment

Big Pharma is an industry where they like their products to fail. Because that means they can sell more stuff to the same clients. A third shot (because the first two didn't work). A booster (just to be sure the third one works really well). More shots, at least one a year, because the virus mutates (systematically becoming weaker and less dangerous, like the latest strain, but don't let the public know that).

Same customers, lifelong income for the makers. Free to the end-user, but raking in the billions for the companies.

Get the whole world involved - astronomical profits.
